Amount of Caffeine in Green Tea -part 2

Comparing Green Tea Caffeine

As we have introduced in our last blog post about caffeine in green tea, green tea caffeine is said to be one third of coffee. Green tea caffeine is said to provide the bitter flavor. This caffeine in green tea will depend on when it was picked. Younger spring green teas are said to contain more caffeine, so high end Japanese green teas such as matcha and gyokuro will contain more caffeine.

Caffeine Compared to Black Tea and Coffee

Japanese green tea is about 1/3rd of caffeine compared to coffee and slightly less than black tea as shown below.

Caffeine among the different type of Japanese Green Tea

The very well known premium tea leaves, Gyokuro, will have the most amount with 160 mg. Next will be the matcha green tea containing 30 mg relatively very low. Sencha and Houjicha will have 20 mg and genmaicha will have the least caffeine with 10mg.

The amount of caffeine that will be in your tea will depend on how you brew the tea, so please use the chart above for reference. As for Japanese green tea, it will be better to brew it at a shorter time to avoid many caffeine to be extracted. The longer you brew basically the more you get the caffeine.
